T+0 Finality

Definition ∞ T+0 finality means that a transaction is settled and irreversible on the same day it is initiated. In financial systems, this implies immediate and absolute confirmation of a transaction, removing any settlement risk or delay. For blockchain networks, it means that once a transaction is included in a block, it is considered final and cannot be altered or reversed. This offers significant advantages in terms of liquidity and risk management compared to traditional multi-day settlement cycles.
Context ∞ The pursuit of T+0 finality is a key objective for many high-performance blockchain protocols and central bank digital currency initiatives. News often compares the finality characteristics of different networks, highlighting how faster settlement times can enable new financial products and services, particularly in wholesale payments and cross-border transactions.
